About High voltage generator
With the economic development and the increasing capacity of industrial power equipment, the capacity of diesel generator sets as backup power sources is also increasing. Sometimes, multiple high-power diesel generator sets are required to be connected in parallel to meet the requirements. The voltage is also increased from the usual 400V to 6300V or 10500V. At this time, the high-voltage diesel generator set came into being, and the demand for high-voltage electrical equipment was solved in time.
Because the output voltage is 10kV and the voltage of the original power supply system is the same, the high-voltage unit can directly access the power supply system, eliminating the investment in equipment for large power supply and distribution systems. At the same time, because the output voltage of the unit is high, the output current is small, and the power loss during the power transmission process is small, which is suitable for long-distance transportation.
The genset is reliable in operation and good in economic benefits.
Comparison between high-pressure diesel generator set and low-pressure diesel generator set
|NO.||Items||Low-voltage diesel gensets||High-pressure diesel gensets|
|1||Power capacity||can be operated in parallel||can be operated in parallel,Generator rooms can be built centrally|
|2||Transmission distance||Short-distance transmission||Long-distance transmission|
|4||Operating costs||Low equipment investment,
Cost low in low-capacity short-distance transmission
High cost in high-capacity long-distance transmission
|High equipment investment, low maintenance cost, and absolute advantage in large-capacity and long-distance transmission and distribution|
|5||Operation and maintenance||easy operation||More complicated. Need professional operation|
|6||Configuration||Simple Configuration||Complex configuration|
|7||Safety performance||Safe, mature technology, low technical requirements||Safe, mature technology, high technical requirements|
|8||Development tendency||High – power generator sets tend to be replaced by high – voltage systems||The demand for high-voltage generator sets is gradually increasing|
